I want to turn off my 3rd stage heat (the aux heat stage called from "W"). Not quite permanently, but semi. I want to disable the furnace's ability to call for aux unless I go turn it back on.
This might be simple, but it's not as simple as you may think. I'm told the circuit breakers for the auz furnace aren't independant of the unit itself. No shutting down a breaker.
However, Dip Switch Pack SW2, switch #5, looks very interesting. it's labeled
Now that sure seems to be telling me 3rd stage heat, but then I'm not too interested in breaking my furnace.
Can anybody tell me:
1) How does one disable, preferable via dip switch (or breaker if it's supposed to be possible) aux heat?
2) And, uh, what's that dip switch I mentioned if not control of aux heat?
I am, by the way, using a carrier ComfortZone II-b controller. There is no "W" wire coming from the thermostat.... Data comm channel heading down to the controller board...
There may be a lead coming from the controller M-board heading to the furnace, but I'm kinda reluctant to start screwing with wires at that point.
